Influxdb Analysis in go Monitoring Scheme

This article introduces the relevant knowledge of "influxdb analysis in go monitoring scheme". In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

influxdb

InfluxDB is an open-source time-series database developed in GO language, especially suitable for processing and analyzing time-series related data such as resource monitoring data.

Since it is a time series database, the data of influxdb has a column named time, which stores UTC timestamp.

The time of each data record is also the main index automatically generated by the database.

If no timestamp is provided for a point, InfluxDB assigns a local current timestamp when the point is fetched.

field key, field value, field set

FluxDB consists of field key and field value.

The set of field key and field value pairs is called a field set.

In influxdb, fields must be present.

Note that fields have no index. If you use fields as query criteria, all field values that meet the query criteria will be scanned, and the performance is not as good as tag. For example, fields are SQL columns without indexes.

tag key, tag value, tag set tag

Tag consists of tag key and tag value.

tag key and tag value pairs form a tag set

tags are optional,

However, it is strongly recommended that you use it, because tags are indexed, and tags are equivalent to indexed columns in SQL.

tag value can only be string type measurement

Measurement is a container for fields, tags, and time columns, equivalent to tables in SQL.

select

Database names are used. Double quotes are used when connecting queries, not normally required
